Susquehanna State Park includes many historic structures, like the water-powered Rock Run Mill with its impressive 32-foot, 12-ton wooden wheel, built around 1794; the Steppingstone Museum, a 19th-century farm site; and the Jersey Toll House, built in 1804. This passing-point for early valley settlers and mansion overlooking the mill have been restored for public access; the Toll House now serves as the park's information center.
The facility offers an abundance of recreational opportunities, including a boat launch, campfire programs, campsites, cross-country skiing, flat water canoeing, hiking and riding trails, pet trail, picnicking, playground, a bowhunting area and archery range. The river offers excellent fishing opportunities, including pike, perch, and bass for shoreline anglers or boating anglers. Campground is open the first weekend in May through the last weekend in September.
